| contents | Reasons for drilling: 1. Obtaining information on the geological section of Pleistocene and Holocene sediments; 2. Study of properties, composition and lithologic-facial features of the sediments. 3. Reconstruction of paleoecological conditions within the Barents and Kara Sea shelf during Cenozoic. Technical results: The hole has penetrated the section of 50 m and stopped in Neopleistocene sediments. Hole description and results: 1. Lithologic and paleontological studies of drill samples from the hole have allowed to reveal lithologic features and to carry out a lithologic and stratigraphic sequence of sediments from Neopleistocene to Holocene ones. 2. Thicknesses of the units are as followed: Neopleistocene ñ 44.8 m, Holocene ñ 5.2 m. 3. The units are heterogeneous. The Neopleistocene unit (from 50.0 to 5.2 m) has five layers. The lowermost layer in the interval from 50.0 to 46.0 m is composed of dense greenish-gray clay with small sand admixture. It is overlain by the layer 46.0-27.0 m composed of dense dark gray ball-shaped loam with rare inclusions of rudaceous material, sand and clay lenses. In the interval from 27.0 to 18.0 m sediments comprise dense dark gray ball-shaped sandy loam with sandy lenses and nests. Sediments in the interval from 46.0 to 18.0 m are interpreted as glacial diamicton. In the interval from 18.0 to 7.8 m there occurs alternation of dark gray clayey sediments with dark gray fine silty mud containing small shell debris. The upper layer of the Neopleistocene unit in the interval from 7.8 to 5.2 m is composed of dark gray clay. The Holocene unit (from 5.2 to 0 m) has two layers. The lower layer 5.2-1.2 m comprises dark gray morainic clay (diamicton) containing, hydrotroilite, small shell debris, sandy nests and lenses. The upper layer 1.2-0 m is composed of dark gray clay with shell debris and hydrotroilite. |
